VR is getting bigger and bigger. More and more customer are asking for experiences for trade fairs and exhibitions. But there is a huge disadvantage: It's a single user experience. Everybody around the main user can merely watch if possible.We therefore started to think about possible alternatives and how to include the people and world around the VR user into the experience.

The first prototype called "Stranger Things", a nod to the tv series of the same name, plays with the concept of parallel worlds. The VR user is placed in a room in which he finds a few objects and a chain of light attached to a wall. Every bulb is marked with a letter. The same wall is placed in the real world. By touching a bulb or the wall close to it, the bulb will start to glow. At the same time the bulb on the mirrored wall will light up too. This creates a fascinating way to communicate. Now both sides have to start communicating with each other, as there are clues in both worlds that, only combined allow to solve a riddle. This way of interaction also attracts a lot of people as it has a lot of long range effect.

The second prototype called "Labyrinth" places the VR user in a digital maze. The player can move around freely and sees the final destination, when looking up. The problem is that he will start to run into dead ends, never able to reach the goal. The people around the VR player have a analog representation of the maze in front of them. It is made of cards and the player can move rows to change the layout of the labyrinth. Both sides need to start communicating with each other now: The VR user needs to describe his surroundings, while the real world players need to describe possible ways. By moving the right walls the vr user is able to proceed to the goal. This is a really exciting way to interact and communicate with each other, as the movement of the analog cards, directly influences and changes the world around the VR player.

Both prototypes depict that the often boring single user experience can be extended, including the people and world around him to create a more immersive experience for everyone.

The project also boasts a combination of many technologies and software: The Unreal Engine, marker tracking, arduino, (self build) sensors and node.js where combined to create this unique experience
